I don't know the price history on these boots to know if they've been much lower before, but this is the lowest price I have seen on these this season anyway.
REI is carrying these snowboots for $104.93 (plus tax) which is the only price I've seen lower than the $112 price at Zappos. Fatwallet generously kicks in 6% Cash Back, so that brings them down to under $100 (plus tax) from the regularly priced $150 price tag. REI is offering free US standard shipping through 2 January. In addition, through 9 December, buyers will enjoy receiving a $20 REI promotional e-gift card (use e-gift card 12 December - 6 January) for purchases of $100 or more.
If you're in the market for some fierce snowboots . . .
Hope this helps.
